| 摘 要： | 利用2008年5月4-20日东莞市探空观测资料,分析该地区夏季大气边界层内的风场、温度场特征进行研究,结果表明:1)各规定层高度主导风向为WNW,其风向频率值大于15%;2)风速随高度的增加而增大;3)接地逆温大约在20:00左右生成,02:00以后逐渐消失,从06:00到17:00没有观测到接地逆温,一天中接地逆温大约维持12 h左右;4)混合层高度在清晨厚度较薄,午后混合层厚度较厚,有利于污染物的扩散。

| Abstract: | Based on the observation data that have been obtained,the vertical characteristic of wind field and temperature field in summer of Dongguan City have been analysed.The results show that: 1) The leading wind of regulation height is WNW direction,whose frequency value is greater than 15%;2) The wind speed increases with the height;3) The grounding inverse temperature appears about 8 PM,after 2 AM gradually disappears.Between 6 AM to 5 PM there isn't inverse temperature.The grounding inverse temperature persis... |
